kernel: Linux kernel: libceph stack out-of-bounds write via crafted OSDMap

A flaw was found in libceph in the Linux kernel. A remote attacker, acting as a malicious monitor, could send a specially crafted OSDMap Object Storage Device Map with an overly long pgtemp or pgupmap entry. This could lead to a stack out-of-bounds write, resulting in a kernel bug and potentially...

The vulnerability of the decode_choose_args() function in the net/ceph/osdmap.c module, which is part of the Linux kernel’s networking functions, allows a hacker to trigger a service failure.

The vulnerability of the decodechooseargs function in the net/ceph/osdmap.c module, which is part of the Linux kernel’s networking functions, stems from an improper check of the specified index, position, or offset in the input data. Exploiting this vulnerability could allow a remote attacker to...
